This study investigated the mathematics teachers’ awareness in the use of mathematical softwares in Secondary Schools in Benue State. The study adopted a survey research design and the study area was Benue State of Nigeria. A sample of 60 mathematics teachers out the entire mathematics teachers in all the government approved secondary schools in the state was used. Purposive and simple random sampling techniques were used in arriving at the number of mathematics teachers used for the study. The instrument for data collection was Mathematical Software Awareness Inventory (MSAI), it had three parts with five items each and was validated by 3 experts. A reliability coefficient of 0.81was arrived at using Cronbach Alpha formula. Descriptive statistics of Mean and Standard Deviation were used for answering the research questions. The study showed that the mathematics teachers in Benue state are not aware of the benefits of mathematical softwares and have not been using them in the teaching of mathematics. The study recommended among others the introduction of mathematical softwares as a core course for all mathematics teachers training institutes.

The quest to attain food security has led to domestication of the previously-termed wild fruits; amongst them Dovyalis caffra (kei-apple) fruits. Radical human lifestyle changesand change in climatic conditions demands that food should not only be for basic nutrition, but also health benefits. This paper purposed to evaluate the nutrition and health levels of Dovyalis caffra fruits at different growth stages using wet chemistry (Titration, pH, and Kjedhal method) and spectrophotometry (UV-VIS and AAS). For Carbohydrates, sucrose and fructose levels decreased with age as glucose levels increased. Both Proteins and Lipid levels decreased with time. The Iron content increased linearly, from 1.04900 ± 0.000005ppm in young fruit to 1.15780 ± 0.000001 ppm in old fruit. While the zinc content increased nonlinearly from0.16384 ± 0.000002 ppm in young fruit to 0.21523 ± 0.000009 in old fruit.Copper levels remained fairly constant as the fruits aged (0.01430 ± 0.000007 ppm) and in cobalt the concentration decreased from 0.05604 ± 0.000005 ppmto 0.03199 ± 0.000006. Only Green (young) Kei-apple fruits indicated positive antioxidant scavenging capacity against DPPH radical at 515nm with an IC50 level of 28.1385 ± 3.2224 μg/mL.

Festus Chioma, Chioma D. Don-Lawson and Ima-Bright Nwoke – May 2019 Page No.: 19-27
New-fangled Co2+, Ni2+ and Cu2+ complexes with novel pyrazine-Schiff base, (C2H2NC2HN)C(O):N=CH(C4H3S) derived from thiophene-2-carbaldehyde and pyrazine-2-carboxamide in ethyl-alcohol have been successfully synthesized. The metallic compounds and their Schiff base ligand were characterized via analytical (complexometric, molar conductivity, magnetic susceptibility and melting point); and spectral (CHNS, FT-IR, UV-Vis 1H and 13C NMR; and ESI-MS) methods. The spectral results corroborates tridentate chelating nature for the Schiff base ligand forming a six coordinate octahedral geometry in 2L:1M mole ratio with Co2+, Ni2+ and Cu2+ ions separately. The metallic compounds assumed monomeric assemblage with assigned geometry validated by magnetic susceptibility values. The molar conductivity data confirms that all the pyrazine-Schiff base complexes are electrolytes of 2:1 mole ratio in dimethylsulphoxide. The metallic compounds demonstrated better anti-bacterial activities compared to the Schiff base, but the Cu2+ complex had the best in vitro activity against all the screened microbes, validating its possibility of exhibiting broad spectrum antibacterial activity.

– A total of 36 Malaria Rapid Diagnostic Tests (MRDTs) were evaluated in the year 2007 using four highly characterized Quality Control (QC) samples at 200p/ul and 2000p/ul dilutions to assess their performance. Twenty-three MRDTs were not locally purchased in the open market in Lagos but were gotten directly from the manufacturers. Malaria Rapid Diagnostic Tests, out of the 23 MRDTs 19 of them are Histidine rich protein based MRDTs while 4 are Plasmodium lactate dehydrogenase based MRDTs 17 (73.9%) MRDTs of the IMRDTs passed while 6 (26.1%) failed Quality Assurance (QA) testing. Thirteen were locally purchased MRDTs (LPMRDTs), only 1 (7.7%) of LPMRDTs passed, while the remaining 12 (92.3%) failed QA testing. Imported MRDTs had mean signal strength of 1.14±0.56 at 200p/µl and 2.26±0.58 signal strength at 2000p/µl, while the LPMRDTs had a mean signal strength of 0.28±0.49 at 200p/µl and0.79 ±0.75 at 2000p/µl. In the year 2013, quality assurance of locally purchased was repeated using 30 MRDTs (22 HRP2 based and 8 pLDH based ) which were part of the MRDTs tested in 2007 were tested using highly characterized QC samples. All the MRDTs tested using 200p/ul and 2000p/ul dilutions passed QA testing (100% sensitive and specific). The mean signal strength at 200p/ul and 2000p/ul were high. There was no significantly difference in the signal strength and performance of the malaria RDTs (P < 0.001). For heat stability testing, all the MRDTs that had 100% sensitivity during the initial QA testing were stored at different temperatures (35oC, 40oC and 45oC) for 6 months. All the MRDTs had 100% positivity. There was a significant improvement in the performance of the locally purchased MRDTs in the year 2013 this result shows that the implementation of MRDTs product testing by WHO has made a great impact in the quality of MRDTs sold in the open market in lagos, Nigeria.

The research was carried out within the Sedimentary terrain of RCCG, Calvary Love Parish 2, Ukpenu, Ekpoma, Edo State, Nigeria. The geophysical investigation involved the Vertical Electrical Sounding (VES) technique using the Schlumberger configuration and Dipole-Dipole Horizontal Profiling. The traverses were established E – W direction cutting across geologic strike. A total of two traverses were established with total length of 90 m and of varying inter-traverse spacing. A total of four (4) VES stations were occupied covering the entire study area. The acquired data were processed and interpreted integrally to elucidate the shallow subsurface geology of the study area. The results were qualitatively and quantitatively interpreted and are presented as sounding curves and geo-electric sections. The results obtained from the VES delineated three geoelectric units which comprise of topsoil, clayey sand and sandstone formation. The 2 D imaging (Dipole-Dipole) gave information on the subsurface characteristic in the area with low apparent resistivity which indicates low competence material. The geophysical data collected using these techniques were processed and interpreted to image the subsurface lithologies of the investigated area. However, various weak zones were delineated by the two techniques and from the comprehensive interpretation it is deduced that the building can fail, if it is constructed within incompetent clay materials and lateral inhomogeneity. The choice of foundation materials, clay content and topography elevation should be put into consideration.

Defatted neem seed cake was adopted as a material for eliminating lead from the aqueous medium without any modification. Two isotherm adsorption models (Langmuir and Freundlich) were applied to evaluate the models of defatted neem cake adsorption processes. Freundlich models strongly supported the adsorption interaction between the adsorbate (lead) and the sorbent (neem seed cake) with a regression correlation of 0.9051 and Langmuir with 0.2472. Defatted neem seed cake is a promising, cheap and eco-friendly agro material that can effectively be used to remove lead heavy metal from aqueous medium.

Maize and rice grains are major components of food security in the diet of Nigerians. It serves as a major source of carbohydrate in both human and livestock sustenance. They are precursor for the release of energy essential in normal body metabolism. In this study, Maize from Mangu (MM), Maize from Doka (DM), Basmati Rice (BR) identified as low carbohydrate rice from India and Foreign Rice (FR) were proximately evaluated by AOAC, (2012) methods. The research showed that Maize from Mangu (MM) contains significant protein(7.05 ± 0.01)%, ash (1.40 ±0.01)%, carbohydrate (73.96 ±0.010)% and fat 4.40±0.01)%, while the Maize from Doka (DM) had protein (6.65±0.01)%, ash (1.30±0.01)%, carbohydrate (71,68±0.01)%, and fat (4.20±0.01)%. Implying that the Maize (MM) had more carbohydrate than of DM, which may be implicated for low carb, this may be attributed to the specie’s capacity to retain relatively high moisture (7.30±0.01%) and fiber (8.43±0.01)%. The evaluation of rice revealed that BR had relatively high moisture (7.6±0:01)%, ash (0.73±0.010)% and fiber (5.00±0.01)% while the FR, had moisture (7.6±0.01)%, ash (0.73±0.10) and fiber (5.0±0.00)%. The low level of carbohydrate in Basmati Rice could be due to it high moisture and ash content. The mineral content in mg/1000g (of Ca, P, Fe, Zn) of the samples are all below the recommended dietary intake per day. The results show that the maize has lower carbohydrate content than rice. The nutritional proximate compositions of the maize samples were higher than that of the rice. The glycaemic index (G.I) of Basmati Rice (55 to70) makes it suitable for diabetic individuals.

The overexposure of animal skin to natural sun rays often display a debilitating effect that may manifest as skin cancers and ulcers. Topical sunscreens creams are applications that are readily used to address the issue of prolong exposure to UVA and UVB rays. Materials, such as clay has been used around the world for centuries by indigenous people as an important medicinal and cosmetic tool. The objective of the study is to evaluate the sunscreen potentials of locally obtained Arrinrasho clay deposit in Barkin Ladi, Plateau State, Central Nigeria, The sampling points were located by GPS corresponding to latitude (09° 51’ 56.4˝ to 09° 28´´ 55.5˝), longitude (008° 51’05.6˝ to 08° 51’11.4˝) and an elevation between (4305 to 4590)ft. The beneficiated and pulverized thermally modified (BPTM) and the non-modified clay samples were tested for microbial contamination. Four sunscreen creams were formulated using standard zinc oxide cream formula and replacing the zinc oxide with the clay sample as the active ingredient. The formulated sunscreen creams were evaluated for topical Sun Protective Factor (SPF) on albino rat’s skin, physical appearance and pH. The formulated creams were compared with commercially used Aloe sunscreen cream with SPF 30. The results indicated that the thermally modified clay sample was free from microbial contamination unlike the non modified clay sample which was found to be contaminated with Staphylococcus aureus and Bacillus specie. The new formulation provided a similar efficacy against sunburn as the commercially used Aloe sunscreen cream with sun protective factor value (mean ± SD) of 5.67 ± 2.57, 5.00 ± 2.22 and 5.00 ± 2.22 for the standard, modified and non modified sunscreen formulations respectively. The BPTM Arrinrasho clays presented a high potential as sunscreen agent

The fruit of Khayasenegalensis plant, family Meliacease, were collected from Pankshin in the month of November and appropriately identified. The seed oil was extracted using steam distillation method, gas chromatography and mass spectroscopy (GC-MS) was performed, antioxidant analysis was done using DPPH according to Brand-William, Gallic and ascorbic acids served as standard. Anti-microbial activities was determined using Agar diffusion method with Gentamicin 10mg/ml serving as standard. The Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined with tween 80 as diluent. The GC-MS indicated the presence of urs-12-ene (C30) and dodecanoic acid (C12) etc. the extract does not show appreciable antioxidant properties and the antibacterial analysis shows that the activity of the oil on organism isolate increase with increasing concentration, the oil inhibited Staphylococcus aureus, Salmonella typhi and E.coli . The oil inhibited all the organism isolate at the minimum concentration of 31.25mg/ml. However the oil displayed bactericidal activities on organism isolate throughout the concentration. The effectiveness of the oil on organism isolate justified the claim among the traditional communities for treatment of ailment such as typhoid, skin rashes, boils and abscesses as plausible.

The time-contact process technique was employed in soybean crude oil purification. The efficiency of the thermally activated Arrinrasho Nanoclays as an alternate bleaching earth in the Deacidification of free fatty acids and the extraction of trace metals within the brackets 30 minutes and 1-5 % loading of adsorbent. Standard investigations of the free fatty acids after the treatment with the test material were in the range of (0.13 – 0.10) % FFA, the costly conventional adsorbent gave an average of 0.15 % FFA at 1% loading. The atomic absorption spectrometric analyses for Arsenic, Copper, Lead, and Iron in both materials were not detectable at the part per million levels. It is possible to extract (18 – 20) % oil from soybean, this oil contains (38 – 40) % proteins, with insignificant amount of cholesterol and its digestibility. These attributes of the soybean oil has rendered it essential for several health reasons. This oil has been considered as source of biodiesel for generating power in energy circles due to its availability.

Global warming is one of the greatest challenges facing the environment today. Recent studies have shown tremendous impact of global warming on climate which is majorly caused by human activities, specifically emission of greenhouse gases. Carbon trading was introduced in order to help curb this menace by encouraging firms to adopt environmental friendly technologies. The pricing and policies for Carbon Emissions therefore influence the “right to pollute” the environment by firms. Agriculture is highly affected by adverse climatic and weather conditions and hence poor production that affects agricultural commodity prices. This study investigated volatility spillover between Carbon Emissions prices and Agricultural commodity prices, with interest in Wheat prices, in the European Union market for the period between May, 2008 and April, 2018. Variable fluctuations over a long period of time are a sign of the volatility of such a variable, whose deviation from the expected value describes that volatility. ARMA-GARCH models were used to model the volatility of each variable that is Carbon Emissions and Wheat. ARMA(0,1)-GARCH(1,1) was the optimal model fitted for Carbon Emissions, whereas ARMA(0,0)-GARCH(1,1) was fitted for Wheat. Both models used student-t distribution as the data portrayed presence of heavy tails. VAR(3) model revealed significant unidirectional Granger causality from Carbon Emissions to Wheat. The study used VARMA-GARCH and VARMA-AGARCHto investigate cross-market volatility spillovers between Carbon Emissions prices and Wheat prices. There were spillover effects from Carbon Emissions market to Wheat market. VARMA-AGARCH is preferred to VARMA-GARCH in modeling volatility spillovers between these two markets.

Generalised Linear Models such as Poisson and Negative Binomial models have been routinely used to model count data. But, these models assumptions are violated when the data exhibits over-dispersion and zero-inflation. Over-dispersion is as a result of excess zeros in the data. For modelling data with such characteristics several extensions of Negative Binomial and Poisson models have been proposed, such as zero-inflated and Hurdles models. Our study focus is on identifying the most statistically fit model(s) which can be adopted in presence of over-dispersion and excess zeros in the count data. We simulate data-sets at varying proportions of zeros and varying proportions of dispersion then fit the data to a Poisson, Negative Binomial, Zero-inflated Poisson, Zero-inflated Negative Binomial, Hurdles Poisson and Negative Binomial Hurdles. Model selection is based on AIC, log-likelihood, Vuong statistics and Box-plots. The results obtained, suggest that Negative Binomial Hurdles performed well in most scenarios compared to other models hence, the most statistically fit model for over-dispersed count data with excess zeros.

The bit-error-rate (BER)is an important factorthat decides the performance of different modulation techniquesof bio-medical wireless system since the objective of any transceivers system is to receive the information with lowest errors because errors reduces the system performance. In this work, BER performance of some of digital modulation schemes (PAM, PSK, DPSK and FSK) are evaluated in additive white Gaussian noise (AWGN) and Rayleigh fading channels at different modulation order. The system is implemented in MATLAB 2018b Simulink environment. The results shows clearly that at 15 dB, FSK modulation scheme at higher modulation order 32 gave better performance with lowest errors (4.91x 10-28) for biomedical RF transceivers system. The mean BER obtained at this highest modulation order is 0.0102 which is very low compared to PAM, PSK and DPSK modulation schemes. Hence, FSK at modulation order 32 would enhance the performance of the Bio-medical wireless system.

In the electric power system for the design, planning, control and operation at the current time and upcoming forecasting expansion of systems the power study or load flow analysis is essential. The effect of interconnections, add or remove generations, loads, transmission lines, etc. known before the installation gives the top, financial and effectual operation. This paper explains about the solution of load flow study considering of input voltage and indication power settings to power system and provides all the busses power flow and voltage magnitude. The calculation of load flow studies is easy for small system. But the system is too large that consists with hundreds or thousands busses it is problematical by hand. The MiPower (MiP) software is used to resolve power flow solution problem since large power system network. To solve the power flow problem in present many software program available for example MATLAB, Power World Simulator (PWS), PSCAD and MiPower but, Mipower is chosen. Because Mipower is best simulation software of power flow studies for bulky network and it is adoptable for like smart grid and smart city applications. And also it gives the detailed and accurate result with less time. The Mipower software is the forward-looking simulation equipment in an attempt to develop the load flow analysis. All the power system tools were designed to survive high effectiveness and to resist worst case situation. It is also has the inbuilt GPS interface due to this software is best for smart grid and smart city applications.

Effects of radiofrequency radiation (RFR) on human health have grown to be of serious health concern, with the entry into daily life of RFR emitting devices such as wireless fidelity, cell phones, masts, radio and television transmitters. Recent studies have reported that RFR exposure particularly during gestation affects the developing fetus. This has been attributed to oxidative stress caused by RFR exposure The aim of the present study was to examine the effects of 2.45 GHz RFR prenatal exposure on semen parameters of the first filial generation (F1) of albino rats. Six pregnant albino rats were equally divided into an unexposed control group (CG) and an experimental exposed group (EG). The rats were confined in Electromagnetic Field (EMF) cages specially designed for this study. An Access Point (AP), consisting of a portable radio (2.45 GHz picostation by Ubiquiti Networks, USA, with its integrated omni-directional antenna) serving as RFR source was placed inside the EG cage in close proximity (15 cm) to the pregnant rats. One (1) hour daily exposure to 2.45 GHz RFR was performed on EG rats on days 13st to 21st of gestation, and a mean electric field intensity of 5 V/m (power density of0.066 W/m2) was maintained for the whole period of exposure. New-CG and New-EG were established from pups obtained from both CG and EG respectively after birth. All male rat pups were sacrificed on 50th day postnatal, and the testes and epididymis were removed for histological examination. Statistical analysis was done for comparison of results using statistical package for social sciences (SPSS version 25). One – sample t-test was chosen for mean comparison test atα <0.05confidence level. Quantitative analysis of Total Sperm Count (TSC) revealed a significant reduction in New-EG (92.3 ± 3.20*) when compared to TSC in New-CG (108.66 ± 4.57). Motility and morphology grading also varied between New-EG(Motile = 79.00 ± 1.68, Non-motile = 21.00 ± 1.68)and New-CG (Motile = 86.70 ± 1.70, Non-motle = 13.30±1.70).Microscopic examination revealed some histological changes such as severe follicle degeneration, severe loss of interstitial cells, spermatogenic arrest, and morphology abnormalities in New-EG rats. The results of this study showed that one (1) hour daily exposure of pregnant rats to 2.45 GHz RFR on days 13th to 21st of gestation has a deleterious effect on the semen parameters of F1 generation.

Military electronic equipment is a subject of various tests determining its resilience to high-altitude electromagnetic pulse at nuclear explosion (HEMP) on special test benches (HEMP simulators). Recently, it has become very important to ensure HEMP protection for civil systems that are part of a country’s infrastructure, primarily, those of the power industry. In the USA for example, a special Directive signed by President D. Trump on March 26, 2019 is devoted to this issue; activities of SC77C Committee of International Electrotechnical Commission; activity of WG C4.54 group within CIGRE. Since military men have extensive experience in the area of establishing HEMP protection and testing of electronic equipment, it is often brought to civil equipment without considering its specific features. Is this correct? The article discusses this issue and suggests that it is not feasible to test electronic equipment used in the power industry on military test benches.

In this study, crude palm oil was used as a precursor for the production of biolubricant base stock by a two-step transesterification process. Palm oil methyl ester produced from the first step was subsequently reacted with trimethylolpropane using calcium hydroxide as catalyst to produce palm based TMP ester. Optimization of lubricant base stock synthesis from palm oil methyl ester and trimethylolpropane was carried out using response surface methodology, central composite design (CCD). The optimum variable conditions were reaction temperature of 159.9oC, mole ratio of 4.99, catalyst loading of 1.16 and reaction time of 211.63 minutes under vacuum pressure for 84.681% palm based TMP ester yield. Regression analysis of the data showed a second order quadratic regression model which establishes the link between variables and biolubricant yield with temperature and mole ratio being most significant variable. The coefficient of regression R2 was 0.9477 implying that 94.77% of the irregularity in the response can be explained by the model. Lubricating properties of palm based TMP ester was evaluated and found to have the following lubricating properties: kinematic viscosity of 40.44 and 10.03 cSt at 40oC and 100oC respectively, viscosity index of 198, flash point of 187oC and pour point of -6oC. These properties of palm based TMP ester conforms to the standard specifications for ISO VG32 and VG46 viscosity grades, and were also found similar to other plant based biolubricants such as jatropha, sesame and canola biolubricant base stock and indicates good prospect as base stock in biodegradable lubricant formulation.
